The TeraFlex JK: Front Track Bar Drop Bracket & Frame Brace Kit addresses many front-end issues prevalent with lifted JK Wrangler/Unlimited models. Highly recommended for JK models with 4in or more lift. The Front Track Bar Drop Bracket lowers the Front Track Bar mounting point to correct steering geometry for superior highway drivability. Multiple track bar mounting holes allow you to fine tune the track bar angle to reduce bump steer and other front-end issues. The Frame Brace and Brace Bar reinforce the frame further reducing front end shimmy and excess frame movement. Compatible with all factory and aftermarket axle shafts, ball joints, wheel hubs, and tie rods. Does not affect operation of factory stability and traction control systems including ESP and ABS.
